 # Amnezia Web Panel
 
-A modern, high-performance web interface for managing **AmneziaWG**, **Classic WireGuard**, **Xray (XTLS-Reality)**, **Hysteria 2**, **NaiveProxy**, **Telemt (Telegram MTProxy)**, **Cloudflare WARP**, **AmneziaDNS**, **AdGuard Home**, **SOCKS5**, and **NGINX + Let's Encrypt** services on remote Ubuntu servers — from a single dashboard. Designed to provide a premium user experience with robust administrative capabilities.

ACME TLS on the domain, per-client basic auth, `naive+https://` share links. Requires free TCP **80** and **443**. **Use Karing** as the client — do **not** use v2rayN; other clients are untested.
     *   **Telemt (Telegram MTProxy)**: High-performance Telegram MTProxy with TLS emulation and comprehensive management (quotas, IP limits, real-time session tracking). Robust install path that auto-configures Docker's official apt/yum repository when needed.
     *   **Cloudflare WARP**: Add and manage WARP-powered connectivity from the panel for routing and network flexibility.
+    *   **NordVPN**: Connect/disconnect outbound NordVPN from Settings via the official CLI (optional country/city).
 *   **🛠 Services**:
     *   **AmneziaDNS**: Internal DNS resolver on a private docker network (`amnezia-dns-net`, IP `172.29.172.254`) to prevent DNS leaks and blockings.
     *   **AdGuard Home**: DNS-based ad blocker with a web admin UI. Two install modes: **Replace AmneziaDNS** (takes its IP, all VPN clients use AdGuard immediately) or **Side-by-side** (parallel deployment on `172.29.172.253`, web UI accessible only over the VPN by default). Optional opt-in checkboxes to expose the web UI / DoT / DoH on the host.

     *   **Reboot** the server directly from the UI.
     *   Strictly concurrent protocol status polling — all supported protocols/services checked in parallel for immediate feedback.
     *   **Asynchronous Processing**: Resilient, non-blocking background architecture prevents the UI panel from freezing, even if remote endpoints hang.
-*   **🔁 Cascade (double VPN)**:
-    *   Route clients through an **entry** AmneziaWG/WireGuard server to an **exit** server (country-block bypass).
-    *   Approach inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade) (AWG2 entry→exit); applied via panel SSH — **no remote curl|bash** script download.
-    *   Handshake wait + optional egress verify (curl --interface → ifconfig.me); exit return route persisted like ryderams vps2.
-    *   Users keep using the **ENTRY** client config only — do not share the exit cascade peer.
 *   **🧩 Marketplace & Templates**:
     *   Market templates provide quick presets for installing and configuring supported protocols and services (including **Hysteria 2**).
     *   Multi-protocol management lets you run and control multiple protocol instances on the same server.
 *   **🌐 Internationalization (i18n)**:
     *   Full support for **English**, **Russian**, **French**, **Chinese**, and **Persian**.
     *   Native **RTL (Right-to-Left)** support for Persian language.
+*   **🔄 Auto-update**:
+    *   Settings → About checks releases on [git.evilfox.cc](https://git.evilfox.cc/test2/Amnezia-Web-Panel-main) and can install the latest tag via git + restart (when the panel runs from a git checkout).
+*   **🌍 Tunnels & outbound VPN**:
+    *   **Cloudflare Quick Tunnel** and **ngrok** expose the local panel to the internet.
+    *   **Cloudflare WARP** and **NordVPN** route the host outbound (no public panel URL).
 *   **👥 Advanced User Management**:
     *   Role-based access (Admin, Support, Regular User).
     *   Traffic limits, status monitoring, and account expiration.

 ## 📋 Fix / changelog (this fork)
 
+### v2.5.4
+*   **Move connections between servers** — on a server page, select configs and move them to another server (recreates peers, keeps user links).
+
+### v2.5.3
+*   **Fix gray Update panel button** — enabled by default; Docker installs allow in-container archive updates when `/app` is writable.
+
+### v2.5.2
+*   **Tunnels UI redesign** — Settings → Tunnels: grouped layout (public access / outbound VPN), provider cards, status pills, responsive grid.
+
+### v2.5.1
+*   **One-click panel update** — Settings → About → **Update panel**: downloads release ZIP from Gitea (or `git checkout` when `.git` exists), runs `pip install`, restarts.
+
+### v2.5.0
+*   **NordVPN in Tunnels** — connect/disconnect outbound NordVPN from Settings (official `nordvpn` CLI; optional country/city).
+
+### v2.4.0
+*   **Auto-update from Gitea**: Settings → About checks https://git.evilfox.cc/test2/Amnezia-Web-Panel-main releases and can install the latest tag via `git fetch` + checkout, then restart (git install only).
+
+### v2.3.0
+*   **Cascade removed** — double-VPN feature dropped from the panel (manager, API, UI, i18n).
+
 ### v2.2.1
 *   **Cascade egress verify fix**: bind curl to ENTRY `awg0`/`wg0` IP (client-subnet policy route), not cascade peer Address.
 *   Soft-warn (no rollback) when policy route via `cascade` is OK but public-IP echo services fail.
 
 ### v2.2.0
-*   **Cascade (double VPN) restored** — stable entry→exit tunnel for AmneziaWG / WireGuard.
-*   Inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade); logic runs over panel SSH (**no remote curl|bash**).
-*   Safety: require exit **handshake** when enabled; optional **egress verify**; subnet conflict check; exit `/32` return route with start.sh markers.
-*   UI on the server page with per-step settings (pin exit route, MSS clamp, verify egress, …). Defaults prefer **awg2**.
+*   **Cascade (double VPN) restored** — later removed in **v2.3.0**.
+*   Inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade); logic ran over panel SSH (**no remote curl|bash**).
 
 ### v2.1.0
 *   **NaiveProxy — stable**: production-ready install (Caddy + klzgrad/forwardproxy), share links always include `:443`.

 ### v1.6.0
 *   **3x-ui multi-panel**: register several 3x-ui servers in Settings; pick a panel and load VLESS inbounds over its API when creating users/invites (share link comes from 3x-ui).
 *   **Docker / CI**: refreshed `Dockerfile` + compose, `.env.example`, CI checks, GHCR image workflow.

+*   **Cascade** was temporarily removed in this release (briefly restored in v2.2.x, removed again in **v2.3.0**).
 *   **WG/AWG backups**: ZIP export of client `.conf` + restore with loading feedback.
 *   **API performance**: in-memory data cache, faster server check/stats.
 *   **Share / guest**: one-tap “Copy key”.
